Synthesis of Green and Pure Copper Oxide Nanoparticles Using Millettia Pinnata Leaf Extract and Their Characterisation
ECS Transactions(2022)
Abstract
Copper oxide nanoparticles (CuO Nps) were synthesized using Millettia pinnata leaf extract via an eco-friendly, cost-effective, reliable, and simple green synthetic pathway and were evaluated for visible light assisted photocatalytic properties by carrying out photocatalytic degradation of dyes. The green synthesized CuO NPs were characterized using various analytical techniques like UV-Visible Spectroscopy (UV-Vis), Fourier-Transform Infrared Spectroscopy (FT-IR), X-Ray Diffractometer (XRD), Transmission Electron Microscopy (TEM) and (EDAX) analysis. The biosynthesis was affirmed by UV-vis spectroscopy exhibiting peak at 290 nm. In FTIR analysis, the chemical bonds corresponds to the phytochemicals responsible for bioreduction activity were identified. Energy dispersive spectroscopy (EDS) showed high intense metallic peak of copper (Cu), oxygen (O) and low intense peaks of carbon (C) due to the capping action of biomolecules of plant extract in CuO NPs formation. The X-ray diffraction (XRD) pattern showed distinctive peaks corresponding to (200), (211) and (310) planes revealing the high crystalline nature of synthesized CuO NPs. The TEM analysis also confirmed that the formed nanoparticles had spherical morphology with uniform symmetry.
